UNDER FRAME FOR CARS.

SPECIFICATION forming part of Letters Patent No. 425,501, dated April15, 1890.

Application filed March 6, 1889. Serial No. 302,159. (No model.)

To @ZZ whom t may concern: I

l Be it known that I, SAMSON FOX, a subject of the Queen of GreatBritain and Ireland, residing at Harrogate, in the count-y of York,Kingdom of Great Britain and Ireland, have invented new and usefulImprovements in the Manufacture and Construction of the Under Frames ofCars, such as are mounted upon bogies o1' otherwise for railway andother rolling-stock, of which the following is a specification.

Under frames of cars being' usually constructed of acombination oftimber and metal are necessarily very heavy and costly, and when ofgreat length require to be strengthened by the addition of truss-rodsand other devices to render them suiiiciently rigid to bear the strainsto which they are subjected, while at the same time such structures arevery costly.

Now my invention is in the manufacture of the component parts and in theconstruction of the under frames of cars such as are mounted upon bogiesor otherwise and of the under frames of railway and otherrolling-stocltgenerally, and has for its object the construction of theunder frame-work of cars such as above` referred to in such wise thatthe necessary strength and rigidity are obtained in a more economicalmanner than heretofore usual. I

attain these objects by constructing suoli under framework of pressedflanged metallic plates-msuch as mild steel-and as illustrated in theaccompanying drawings, in which similar letters represent similar partsthroughout the several views.

Figure l is a longitudinal sectional eleva tion in part on the line 1 1of Fig. 2, showing the side sills in two lengths and joined at theflanges by rivets of under framework according to my invention. Fig. 2is a plan, also in part. Fig. 3 is an end elevation. Fig. Ll is atransverse section at O O, Fig. l. Fig. 5 is a transverse section at XX, the center of the length of the frame-work.

A A are the side sills, shown to be flanged all round on the outsidethereof, and being of greater depth in the middle than at the ends I amable to dispense with trussbolts.

B is the head-stocl;, which, in conjunction with the parts C, D, I-I,and I, comprises the end sill, of which there is one ateach end of theframework.

I-I H2 are transoms between the two outside sills A A, with a part H3 inthe center for the reception of the king-bolt H4. Beneath 'the part H3,and attached to it and to the transoms Il and H2, is the upper part ofmy improved central swivel-plate D and F are intermediate transoms forconnecting the side sills A A at suitable distances apart. j

E is a broad, transom in the center ot the length of the side sills AAthat is, at the junction of the two parts comprising each of the saidside sills. Gr is a similar transoml to E (but narrower) at the bottomedge of and at the said junction of the respective side sills.

.I .I are longitudinal stays, and form connections between thehead-stocks or end sills B and the transoms II.

K K K K are longitudinal stays connect ing the transoins H2 to thetransoms F and the transoms F to transoms D.

It will be obvious that the arrangement of the component parts of theunder 'frame-work as hereinabove described may be varied to suitcircumstances without departing from the nature of my invention.

What I claim isl. In the construction of railway and other rollingstock,the combination, with the side sills, of the end sills, each consistingof the parts B, C, D, II, and I, ilanged and secured to each other andto the side sills, substantially as described.

2. In the construction of railway and other rolling-stock, thecombination, with the side sills, of two transoms II and II2 and a partI-I3 in the center for the reception ot the kingbolt, all flanged andsecured together substantially as described.

3. In the construction of railway and other rolling-stock, thecombination, with the side sills consisting each of two parts joined atthe center, of a broad transom flanged and secured to the two partscomprising the side sills at their junction, substantially as described.

a. In the construction of railway and other rolling-stock, thecombination, with the side IOO sills consisting` each of tWo partsjoined at broad and narrow transoins at the center of thel center, of abroad transom and a narrow the oai', all flanged and secured togethersubtransom, said transoms being anged and se` stantially as described.
